On the contrary, I work at BigCorp where every machine is locked down - no administrator access, no sudo, etc. People routinely install programs to C:\ simply because it is writable. If you need admin access to install it? Forget it, open an IT ticket.

I've never heard of anyone quitting because of this issue.

Yes. BigCorp have very limited access to resources depending on their role. IF you need to install software OR require admin rights your ticket have to pass long tail of approvals with lots of justification.
